hey everybody,
Thanks for your reply.
I am using the same Network ID for Real Servers & for LVS server.I am having
only one Lan Card on each machine.
I just have to put these entries in /etc/sysctl.conf for real servers to
work or I have to do something more.
net.ipv4.conf.eth0.arp_ignore = 1
net.ipv4.conf.eth0.arp_announce = 2
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
I am using ultramonkey configuration examples for building Apache Load
Balancing Servers and will be soon working on Mysql High Availability
Clustering.
Thanks & Regards
